A visitor can know the exact address of a building and still get lost five minutes after arriving.
That happens often in office complexes, medical buildings, schools, municipal facilities, warehouses, apartment properties, mixed-use buildings, and other large commercial spaces. The problem usually is not a total lack of signs. More often, the property has signs that were added one at a time without a clear system.
A directory may list tenants but provide no clue which hallway to take. A directional arrow may point toward an elevator, but the next floor has no follow-up sign. Room numbers may exist, yet the numbering pattern makes little sense to a first-time visitor. Parking signs may be clear to property staff but confusing to someone who has never been there before.
Good wayfinding signs solve these problems by giving people the right information at the right moment.
For a large building, that requires more than installing a few arrows. The property needs a connected sign system that starts before a visitor enters the building and continues until they reach their destination.
At Gogi Signs, we have worked with New Jersey businesses and commercial properties since 2005. Large-building sign projects have taught us that the strongest wayfinding systems begin with one simple idea: follow the visitor’s actual journey, not the floor plan alone.
This guide explains how to build that system.
What Wayfinding Signs Are Supposed to Do
Wayfinding signage helps people understand where they are, where they need to go, and what decision they should make next.
That sounds simple, but large properties create several different kinds of questions.
A visitor may need to know:
- Is this the correct building?
- Which entrance should I use?
- Where is visitor parking?
- Which floor is the company on?
- Should I take the elevator or stairs?
- Which hallway leads to Suite 420?
- Where is reception?
- Which door is the conference room?
- How do I get back to the main entrance?
- Where is the nearest accessible route?
A complete wayfinding system answers these questions in sequence.
This is why directional signs should not be planned as isolated products. Each sign is part of a chain of information.
If one link in that chain is missing, the visitor may still become confused even though the building contains plenty of signage.
For a broader look at how identification, branding, interior signs, parking signs, and directional signs work together, see our complete guide to business signage for commercial properties.
Large Buildings Need More Than Directional Arrows
Directional arrows are only one part of wayfinding.
A useful system usually combines several sign functions.
Identification signs
These tell visitors what a place is.
Examples include:
- Building names
- Entrances
- Lobby identification
- Floor numbers
- Suite numbers
- Department names
- Room identification
- Restrooms
- Elevators
- Stairwells
Directional signs
These tell visitors which direction to travel.
Examples include:
- Lobby →
- Elevators ←
- Suites 300–340 →
- Conference Center ↑
- Visitor Parking →
- Shipping & Receiving ←
Directory signs
Directories help visitors understand where destinations are located within a larger property.
They may be placed:
- near the main entrance
- in the lobby
- beside elevators
- at major hallway intersections
- at parking entrances
- within multi-building campuses
Regulatory and accessibility signs
Some signs serve legal, safety, or accessibility functions rather than general wayfinding.
Depending on the property, these may include ADA room identification, accessible routes, parking signs, exits, and other required signs.
Orientation signs
Large campuses, hospitals, schools, industrial properties, and multi-building developments may also need maps or “You Are Here” signs.
These help people understand the relationship between several destinations instead of simply following one arrow.
A good system uses the right type of sign for each decision.
Start With the Visitor Journey
One of the easiest ways to find wayfinding problems is to walk the property as if you have never been there before.
Staff members often stop noticing confusing areas because they already know the building.
A first-time visitor does not have that advantage.
Instead of asking, “Where can we install directional signs?” start with:
What does a visitor need to know from arrival to destination?
A typical journey might look like this:
- Find the property.
- Enter the correct driveway.
- Locate visitor parking.
- Identify the correct building entrance.
- Enter the lobby.
- Find the directory.
- Identify the correct floor.
- Reach the elevator.
- Exit on the correct floor.
- Choose the correct hallway.
- Find the suite or department.
- Return to the lobby or exit afterward.
Every step can contain a decision point.
Those decision points are where signage matters most.
What Is a Decision Point?
A decision point is any location where a visitor must choose what to do next.
Examples include:
- a fork in a driveway
- two building entrances
- a parking-lot intersection
- a lobby with several corridors
- an elevator bank
- a hallway intersection
- a stair landing
- a floor with multiple departments
The sign should appear before or at the decision, not after it.
This sounds obvious, yet it is a common problem in commercial buildings.
A visitor reaches an intersection, chooses a direction, walks 50 feet, and then sees a sign confirming they should have gone the other way.
The sign contains correct information, but it arrives too late.
Gogi Signs Insight
When reviewing a large property, we pay close attention to places where people naturally slow down, stop, turn, or look around. Those moments often reveal where directional information is missing. The best sign location is usually tied to a decision, not simply an available wall.
Build the System From the Outside In
Wayfinding starts before someone enters the building.
For large properties, it helps to plan signage in layers.
Layer 1 — Property Arrival
The first layer helps people identify and enter the property.
Possible signs include:
- Monument signs
- Building identification
- Campus identification
- Parking entrance signs
- Vehicle directional signs
- Visitor parking signs
- Delivery signs
- Building-number signs
A large interior wayfinding program cannot fix a confusing arrival experience.
If drivers cannot tell which driveway to use or which building they need, the problem begins before they ever see the lobby directory.
Layer 2 — Entrance and Lobby
Once people enter, they need immediate confirmation that they are in the right place.
Useful signs may include:
- Main entrance identification
- Building directory
- Reception sign
- Floor directory
- Elevator direction
- Stair direction
- Department direction
- Visitor instructions
The lobby is one of the most important points in the system because many visitors mentally reset after entering the building.
They may know they need “Suite 525” but have no idea whether that means the fifth floor, Building 5, or Corridor 5.
A clear directory should remove that uncertainty quickly.
Layer 3 — Vertical Movement
Multi-story buildings need consistent information around elevators and stairs.
Visitors should be able to answer:
- What floor am I on?
- Which floor do I need?
- Which destinations are located here?
- Where do I go after leaving the elevator?
Common signs include:
- Floor identification
- Elevator directories
- Stair identification
- Directional signs outside elevators
- Department lists
- Accessible-route information where appropriate
A recurring problem is placing a good directory in the lobby but providing no confirmation after the visitor exits the elevator.
The person reaches Floor 4 and sees three hallways.
The original directory is now several floors away.
Wayfinding needs continuity.
Layer 4 — Hallways and Departments
As visitors get closer to their destination, the information should become more specific.
Early signs may show broad destinations:
- North Wing
- Medical Offices
- Administration
- Conference Center
Later signs may show:
- Suites 410–430
- Human Resources
- Conference Rooms A–D
- Suite 418
This gradual increase in detail prevents signs from becoming overloaded.
A lobby sign does not need to list every individual room in a 200-room building if visitors can first be directed to the correct floor or wing.
Layer 5 — Final Destination
The last sign confirms arrival.
Examples include:
- Suite identification
- Department signs
- Office signs
- Room signs
- Reception identification
- ADA room signs where required
This final confirmation matters because visitors should not need to guess whether the unmarked door beside Suite 412 is actually Suite 414.
Use a Clear Information Hierarchy
One of the biggest challenges with custom wayfinding signs is deciding how much information belongs on each sign.
Large properties have many destinations.
Putting all of them on every directory usually makes the system harder to read.
A better approach is to organize information by hierarchy.
Primary information
The most important destinations or directions.
Examples:
- Main Lobby
- Building A
- Emergency Department
- Visitor Parking
Secondary information
Groups of destinations.
Examples:
- Suites 200–240
- Administrative Offices
- Conference Rooms
- East Wing
Tertiary information
Specific rooms, departments, or suites.
Examples:
- Suite 214
- Room 3B
- Accounting
- Conference Room C
The farther the visitor moves through the building, the more specific the signs can become.
This keeps early decision points simple.
Develop a Naming System Before Designing the Signs
Wayfinding problems are not always sign-design problems.
Sometimes the building itself uses confusing names.
Consider a property where signs refer to:
- West Building
- Building 2
- Tower B
- Phase II
If all four names refer to the same place, visitors will struggle regardless of how attractive the signs are.
Before designing the sign family, standardize how destinations are named.
The same rule applies to:
- floors
- wings
- suites
- entrances
- departments
- parking areas
- stairwells
- buildings
If the elevator directory says “North Wing,” the hallway signs should not suddenly call it “Building North.”
Consistency in language is just as important as consistency in colors and typography.
Room Numbering Should Help People Predict Where They Are
Room and suite numbers can support the wayfinding system.
A common approach is to connect the first digit to the floor:
- 101–140 on Floor 1
- 201–240 on Floor 2
- 301–340 on Floor 3
The exact numbering structure depends on the building, but the principle is useful: numbers should follow a pattern that people can learn.
Long corridors may also benefit from predictable sequences.
If Suite 201 is beside Suite 240 while Suite 202 is at the opposite end of the building, signs will have to work much harder to explain the property.
When possible, logical numbering and good signage should support each other.
Typography Should Be Readable Before It Is Decorative
Directional signs are functional tools.
Their typography has to be understood quickly.
Consider:
- letter size
- viewing distance
- contrast
- capitalization
- spacing
- line length
- font weight
Decorative typefaces may work for a lobby logo but perform poorly on a directional sign that must be read while someone is walking.
The sign family can still match the brand without using the exact same typography everywhere.
For example, a company may use a distinctive brand typeface for identity signs while using a simpler companion typeface for directories and directional information.
The priority is clarity.
Arrows Need Their Own Visual Logic
An arrow is one of the smallest elements on a directional sign, yet poor arrow use can create major confusion.
Keep arrow treatment consistent throughout the property.
Avoid mixing:
- several arrow styles
- different arrow sizes without reason
- arrows placed randomly before and after text
- ambiguous diagonal directions
The relationship between arrow and destination should be obvious.
Where several destinations share one direction, group them together.
For example:
→ East Wing
→ Suites 420–460
→ Conference Center
is easier to scan than repeating arrows across a poorly structured layout.
Color Can Organize a Large Property
Color can help distinguish buildings, floors, wings, parking zones, or departments.
For example:
- Blue — North Wing
- Green — South Wing
- Orange — Conference Center
This can be useful in campuses and larger facilities, but color should support the information rather than carry it alone.
A visitor should not need to remember that “green means Building C” without seeing words or symbols.
Color systems also need enough contrast for readability and should be considered alongside accessibility requirements.
Use color as a secondary cue.
Icons Can Reduce Reading Time
Recognizable symbols can help visitors identify common destinations quickly.
Typical uses include:
- restrooms
- elevators
- stairs
- parking
- information
- accessibility
- food
- exits
Icons are particularly helpful in properties serving a broad public audience.
Still, not every destination has a universally understood symbol.
An abstract icon for “Human Resources” may create more confusion than the words themselves.
Use symbols where their meaning is clear.
Wayfinding Signs Should Match the Building
A corporate office tower, children’s medical facility, warehouse, school, and luxury apartment building should not all have the same sign style.
The sign family should reflect:
- architecture
- brand character
- interior finishes
- audience
- maintenance needs
- property use
Possible materials may include:
- acrylic
- aluminum
- dimensional letters
- printed panels
- vinyl graphics
- wall-mounted sign systems
- changeable directory systems
The choice should be based on where the sign is installed and how often the information is likely to change.
A multi-tenant directory may need replaceable tenant inserts.
A permanent floor identifier may use a more fixed construction.
A warehouse directional sign may value durability and immediate readability over decorative detailing.
Plan for Change
Large buildings rarely stay exactly the same.
Tenants move.
Departments change names.
Companies expand.
Rooms are reassigned.
Parking rules change.
A wayfinding system should account for this where possible.
Ask:
- Which signs contain permanent information?
- Which signs will change frequently?
- Can tenant names be replaced?
- Can directories be updated without replacing the whole sign?
- Will new departments fit within the system?
- Is there room for future destinations?
This does not mean every sign needs changeable components.
It means change should be anticipated rather than treated as a surprise.
ADA Signage and Wayfinding Are Related but Not Identical
Wayfinding and accessibility often overlap, but not every directional sign is an ADA room sign, and not every ADA sign performs a directional role.
Certain permanent rooms and spaces may require signage with specific characteristics such as raised characters, Braille, mounting locations, contrast, and other requirements.
Directional and informational signs may have their own accessibility considerations.
Because requirements depend on the sign and application, accessibility should be reviewed during planning rather than treated as a visual style added after design.
For large properties, ADA signage also needs to fit into the broader sign family so required signs do not look like unrelated additions.
Exterior and Interior Wayfinding Must Agree
A surprisingly common problem is a disconnect between exterior and interior terminology.
The parking sign directs visitors to “Building B.”
The entrance sign says “West Pavilion.”
The lobby directory lists “Professional Offices.”
These may all refer to the same part of the property.
A connected system uses the same destination names from arrival to final room.
The visitor should not have to translate the property’s internal vocabulary.
Do Not Forget the Return Journey
Most wayfinding planning focuses on getting people to a destination.
Visitors also need to leave.
After a meeting, appointment, or event, they may need to find:
- elevators
- lobby
- main exit
- parking garage
- rideshare pickup
- another building
A hallway that was easy to follow in one direction may look completely different on the way back.
Look at both directions during a site walk.
Test the System With Someone Who Does Not Know the Building
One of the best tests for a sign program is also one of the simplest.
Give a destination to someone who does not regularly use the property.
For example:
“Start at the visitor parking lot and find Conference Room 4B.”
Then watch.
Do not give directions.
Notice:
- where they pause
- where they look for signs
- where they choose incorrectly
- which signs they miss
- which destination names confuse them
- whether they can return without help
These observations reveal problems that may be invisible to people who know the property well.
Common Wayfinding Mistakes in Large Buildings
Adding signs only after complaints
Complaints are useful clues, but a property should not need years of visitor confusion before developing a sign plan.
Too many signs
More signs do not automatically make directions clearer.
Too much information can create visual noise.
Too few confirmation signs
Visitors need reassurance after major transitions such as elevators, stairways, and long hallways.
Inconsistent destination names
The same place should use the same name everywhere.
Signs placed after the turn
Directional information needs to arrive before the visitor commits to a direction.
Tiny text
A directory that requires visitors to stand inches away is not doing much for people approaching from across a lobby.
Poor contrast
Brand colors should not make information difficult to read.
No plan for updates
Directories and tenant signs become messy quickly when new names are patched over old systems.
Treating ADA signs as a separate project
Accessibility signage should be considered with the rest of the interior sign plan.
Forgetting staff and operational movement
Visitors are not the only users. Large properties may also need directions for:
- employees
- deliveries
- contractors
- vendors
- service crews
- truck drivers
A Practical Wayfinding Planning Checklist
Before approving a large-building sign program, review these questions.
Property arrival
- Can visitors identify the property from normal approach routes?
- Are parking and entrances clear?
- Are building names consistent?
Lobby
- Can a first-time visitor find a directory quickly?
- Does the directory show destinations in a useful hierarchy?
- Are elevators and stairs easy to locate?
Floors and hallways
- Is the floor clearly identified?
- Are directions available immediately after elevators and stairs?
- Are major hallway intersections signed?
- Are suite ranges logical?
Destinations
- Are suites, rooms, and departments clearly identified?
- Are permanent-room signs reviewed for accessibility requirements?
- Do final destination signs confirm arrival?
Design
- Is text readable from expected distances?
- Is contrast strong enough?
- Are arrows consistent?
- Are colors and icons used consistently?
- Does the sign family fit the building and brand?
Long-term use
- Can frequently changing information be updated?
- Can new destinations be added?
- Is the system documented so future signs match?
Testing
- Has someone unfamiliar with the building tested the route?
- Can visitors find their way back out?
- Have common visitor questions been considered?
When Custom Wayfinding Signs Make the Most Sense
Off-the-shelf directional signs can work for simple needs.
Large commercial buildings often require a more planned approach because they have:
- unique architecture
- multiple tenants
- custom brand standards
- several floors
- unusual circulation patterns
- changing directories
- multiple entrances
- public and staff-only areas
- accessibility requirements
- interior finish standards
Custom wayfinding signs allow the information hierarchy, materials, dimensions, mounting, colors, and sign types to be designed around the actual property.
The goal is not customization for its own sake.
The goal is to make the building easier to understand.
A Good Wayfinding System Should Feel Almost Invisible
Visitors usually notice wayfinding when it fails.
When it works well, they simply reach the right place.
That is the standard to aim for.
A large-building sign system should:
- introduce the property clearly
- guide people at decision points
- confirm that they are still on the correct route
- use consistent destination names
- present information in manageable steps
- identify the final destination
- help people find their way back
- allow reasonable updates as the property changes
The process begins by studying how people move through the property.
Not every wall needs a sign.
Not every sign needs five destinations.
Not every visitor needs the same information.
The strongest systems give people enough information to make the next correct decision—and then provide the next piece when they need it.
Gogi Signs has been designing, producing, and installing commercial signage for New Jersey businesses since 2005. If your building has outgrown a collection of disconnected directories and arrows, a property-wide wayfinding plan can turn those individual signs into one clear system.
